I am a bit worried about the experiments of my current roommate, i
know he is a very competent engineer but he has the habit of playing
with lasers.
Now he has a dvd burner laser inside a penlight housing which can
reach across the park here (and that's VERY far, but i'm worried about
he (or me) accidently staring into the beam and i can imagine if it
burns dvd's it will burn eyeballs, or not?
So, my question is if there are glasses... one can use to protect from
laser radiation.
Or am i on a wild goose chase and is it not as bad as i hear everywhere?

You're correct to be worried. DVD burner laser diodes can be as much
as 50 times more powerful than a legal laser pointer (5 mW).

Even a momentary flash in the eye at close range can cause permanent
damage.

There are laser safety goggles that can be worn, but they aren't cheap
or terribly fashionable.
